Abstract: A nut shelling apparatus including a back plate having a first roughened surface on one side, a rocker plate rotatably connected to the back plate and having a second roughened surface on a side adjacent the first roughened surface of the back plate, and a nut inlet connected to the back plate so as to open to a nut-receiving space defined between the roughened surfaces of the back plate and the rocker plate. The roughened surfaces are diamond plate surfaces. A skirt is affixed to the back plate and extends outwardly therefrom so as to be adjacent an outer edge of the rocker plate. The rocker plate is a concave member. The concave member includes a shaft which is rotatably connected to the back plate.
